Well, first of all, I used to have Airtime 2.0.2 in the very same server without problems - but, with apt-get upgrade came some issues witch at this point prevent me from using Airtime at all.
On install I got failure due /etc/php5/conf.d/airtime.ini already existing - okay, this was very simple to get around, but on next attempt install completely freezes on liquidsoap configuration generation. I'm starting to suspect that python version might be an issue here, but I would like to have some confirmations...
After unsuccessfull install I had to run dpkg --configure -a to get things back into somewhat orderly state. But again, uninstall stucks and won't complete. For some reason I cannot determine the cause, might have something to do with my password-protected ssl certs and apache not getting restarted?
Ahh.. figured out what was the problem - it was my rather complicated apache configuration after all - when I got that sorted out, all other parts started to work properly - it feels good to be back on the air :-D
